摘要： A circuit for detecting a phase error between a clock signal and a beam position includes a beam generator, sensor, and phase detector. The beam generator directs a beam toward a beam sweeper in response to a clock signal. The sensor, which is disposed at a mid line of a region that the beam sweeper scans, detects the beam from the beam sweeper, and the phase detector detects an error in the clock phase from the detected beam. Such a circuit can automatically detect the phase error in the pixel clock and correct this error, thus eliminating the need for a manual phase-error corrector.

摘要： A device for driving a plant such as a beam scanner includes a memory, drive-signal generator, and a calibrator. The memory stores data corresponding to the drive signal, and the generator generates the drive signal from the data and couples the drive signal to the plant. The calibrator measures a response of the plant to the drive signal, calculates a difference between the measured response and a corresponding target response, and reduces the difference by altering the drive signal. Such a device can force the output response of the driven plant to equal a target output response, or to be sufficiently close to the target response for a particular application, while the device is operating in an open-loop configuration. Furthermore, while operating in an open-loop configuration, such a device often has a greater stability margin and greater noise immunity than a comparable device that operates in a closed-loop configuration.
摘要翻译：用于驱动诸如光束扫描仪的设备的装置包括存储器，驱动信号发生器和校准器。存储器存储对应于驱动信号的数据，并且发生器从数据生成驱动信号并将驱动信号耦合到工厂。校准器测量工厂对驱动信号的响应，计算测量响应和相应的目标响应之间的差异，并通过改变驱动信号来减小差值。当设备以开环配置工作时，这样的设备可以迫使被驱动设备的输出响应等于目标输出响应，或者足够接近特定应用的目标响应。此外，在以开环配置工作的情况下，与在闭环配置中操作的类似设备相比，这种设备通常具有更大的稳定性裕度和更大的抗噪声能力。

摘要： A projection apparatus memorizes settings as a function of location, orientation, elevation, or any combination. The projection apparatus recalls the settings when the location, orientation, elevation, or combination of the projection apparatus matches memorized values. Memorized settings may include projector settings, image source settings, audio output settings, audio source settings, and the like.
